' To all whomit may concern:

lBe it known that I, AAGE JENSEN, a citizen of the United States, residing at Eureka,`

in the county of Humboldt and State of Cali# fornia, have linvented new and useful Improvements 1n LlquldvRipeners, Pasteurizers,

and Coolers, of vwhich the following is a speci- -iication.

The object of the present invention is to provide an apparatus 'for ripenin cream, or for asteurlzlng milk, cream or ot er liquids,

or or heating orcooling `liquids in general,

which is cheap and simple 'in construction, and convenient in operation, and which can be used interchangeably for any of the above purposes. g I

A further objectvof the invention is to provide an apparatus of this character by means of which a liquid can be firstv pasteurized,VY

and then cooled, without the necessity of exposure to the atmosphere, or of any action which would tend to contaminate theliquid.

' In the accompanying drawing, Figure 1 is a broken sideview, partly in section, of my improved apparatus;`Fig. 2 is an enlarged broken end view of the same, and Fig. 3 .a similar longitudinal section of a bearing; Fig. 4 is a lbroken transverse section; Fig. 5 is a cross section of thesame. V.

Referring to the drawing, 1 indicates the casing of a'receptacle, mounted u on legs 2, the stavesof said casing being he d in place by one or more straps 3. Each end 4 of the casing is apertured and in said apertures are bearings 5, forA hollow shafts 6,' 7. Said shafts are connected at their inner ends with sleeves 8, 9, which are cohnected by a tube 10, extending longitudinall machine, the 'purpose Aof t 's tube being merely tobrace and stren then the moving parts of the machine. It is therefore close against; the passage of fluid by means of blocks 11. Into the sides of said sleevesare screwed pipe sections 12, which extend radially from said sleeves, and with the other ends of lsaid pipe sections are connected the ends of a helical coil'13.

A rotary motionisimparted to said shafts and to said coil by means of a bevel gear 16 mounted upon a shaft 7 and meshing with a bevel pinion17 u on a transverse horizontal shaft l8 mounte in a box 19 secured upon an end of the casing and carrying tight andloose pulleys 20 and 21, by means of which the apparatus can be rotated from any distant source of power.

However, for the purpose o .generally preferred to use a steam injector,

' corresponding sleeve,

through the 'one with an annular tongue 'the receptacle. By

. provides anapparatus vcan be employed interchangeabl cream ripener, as a pasteurizer fr-'giWith the v hollow shafts 6, 7, at opposite ends of the machinev are connected through stuffing boxes 22 pipes 23, 24, which are connected by vertical pipes 2 5, 26 with a returnY pipe 27, having therein a check valve 28, thereby providing a complete fluid circuit. These vertical pipes are suitably supported by means of braces. 29 extending from the ends of the casing. With the pipe 25 at one end are connected pipes 32, 83, controlled by valves 34, 35, and which may be connected with sources of supply of cold water, or brine, oi' other cooling fluid, or a heating fluid.

f heating, it is shown'at 36, controlled by a valve 37, which notvonly supplies heat to thelhelical coil but also causes the liquid to circulate therein. The other vertical pipe 26 isextended at the top and carries an overiow vessel 38, with an overiiow pipe 39. This is used to provide any desired pressure in the coil. j

The receptacle is provided with hinged lids or covers 40. 'In order to discharge the liquid from'the interior of the receptacle it is formed with a discharge passage 41 controlled by a gatevalve 42.

The interiorl of the receptacle is provided withL a lining 43 of a metal which is not in urious to the liquids containedtherein and each bearing 5 is formed with allange 44 secured by rivets or otherwise to said linmgso as .to make a iluid tight connection therebe-v tween. The inner endv ofeachbearing abuts against theadjacent -end of the adjacenty sleeve, said surfaces, ofeach'bearing and the being. provided, the

with anannular groove 46, thus forming an 'annular joint 'for preventing the passage of fluid therebetween. In order to linsure a tight fit'of said joint, there are provided adjusting screws 47 which are screwed through a plate 48, secured upon one of the heads of screwing-11p said screws, said surfaces can be brought close., together and at the same time the pressure is transmitted to the other end -of the tube 10 caus-V fit tightly' against the ing the other-sleeve to adjacent bearing in said end.

' It `will be seen that the'above construction vwhich is simple and cheap, 'and yeteffective, and which can be used to great advantage in small dairies, as 1t either .as a

4.5 and the other or milk and cream, or as a cooler by suitably connecting the supply pipes with hot or cold liquids o the proper temperature.

The form of the coil is very effective for transmitting heat orV cold to the liquid contained in the receptacle for two reasons, first, that, in the rotation of the coil, each part of the liquid brought into actual contact with some part thereof; and, secondly, a coil of this helical form, when rotated, produces a longitudinal, circulatory movement of the liquid, said liquid being thereby forced to one end of the receptacle, then outwards and then returning in the outer portion thereof. Hence all parts of the liquidare quickly brought into close contact with the coil, and heat or cold are quickly and efficiently abstracted therefrom. Moreover, on account of the tube being perfectly smooth and round and free from sharp angles, it is readily maintained perfectly clean, a condition which is absolutely essential in dairy operations. But the most important feature-of the present invention is, that the construction enables a liquid such as 'milk or cream to be first pasteurized by maintaining it for a sufficient length of time at a suitable high temperature, and while still contained in the same receptacle and without any exposure to the outside atmosphere, the liquid can be cooled to the proper temperature, by shutting off the supply of steam and other heated fluid, and passing through the same coil a `suitable cooling Huid.

I claim 1. In an apparatus of the character described, the combination of a suitable receptacle for containingthe liquid to be treated, a pipe therein in the form of a helical coil, connections with the ends of said pipe extending to the outside lof the receptacle, means for rotating said coil, and means for conducting a heating or cooling medium into one end of said coil and out from the other end thereof, substantially as described. i
